Performance Lab NutriGenesis Multi for Men Review (2026): Is It Worth It for Coeliacs?

Full disclosure: I used to work at Performance Lab, they’ve sent me free products since I left, and I earn a commission if you buy through links on this page. It doesn’t cost you anything extra. I’ve used everything I write about here, and I’m honest about what I would and wouldn’t pay for.

Short version: Performance Lab NutriGenesis Multi for Men is gluten free, vegan and well made, with a solid dose of vitamin D, zinc and the B vitamins. It’s also expensive, it’s four capsules a day, and it’s light on the two minerals coeliacs most often run short of: iron and calcium. Worth it if you want a quality all-rounder. Not a fix for a deficiency your GP has found.

Last checked: September 2026, against Performance Lab’s UK product page and NHS guidance. Prices change, so check before you buy.

I’ll be upfront about where I’m coming from. I worked in-house at Performance Lab, and I took this multi for months after my coeliac diagnosis. I wanted a backstop. When your gut has spent a couple of years not absorbing things properly, you start wondering what else you’re short of, and a daily multi felt like sensible insurance.

Did I feel like a new man? No. I didn’t notice anything obvious, and I’d be wary of any review that promises you will after a couple of weeks. A multivitamin isn’t meant to hit like a double espresso. It’s there to quietly cover gaps, and the only proper way to know whether it’s doing that is a blood test.

What I can tell you is that it sat fine with my gut, IBS included, and four capsules a day never bothered me. The rest of this review is the bit you can’t feel: what’s on the label, where it’s strong, and where it leaves gaps a coeliac should know about.

Is NutriGenesis Multi for Men gluten free?

Yes. Performance Lab’s UK product page says it’s “free of gluten, caffeine and artificial additives, colours and preservatives”, and contains no soy, peanut, tree nuts or wheat. It’s vegan too. The capsules are made from pullulan (fermented tapioca) rather than gelatine.

What’s actually in it?

A serving is four capsules, and a box holds 30 servings, so one box lasts a month. Performance Lab lists 24 vitamins and minerals plus inositol and boron. The idea behind “NutriGenesis” is that the nutrients are cultured with the cofactors they’d come with in food, rather than being bare synthetic isolates. Performance Lab says that improves absorption. I haven’t found independent research comparing NutriGenesis with ordinary vitamin forms, so treat that part as the company’s claim.

The bits that matter most, from the label on the UK page:

Nutrient	Per 4 capsules	What that means
Vitamin D	25 mcg (500% NRV)	More than double the NHS’s 10 mcg a day advice, well under the 100 mcg daily upper limit
Vitamin K (K1 and K2)	100 mcg (133% NRV)	A useful pairing with vitamin D
B vitamins incl. B12 and folate	Well above 100% NRV	Generous, which suits a gut that doesn’t always absorb well
Zinc	15 mg (150% NRV)	A solid dose
Iodine	150 mcg (100% NRV)	Covers the daily reference amount
Iron	A small amount (well under half the NRV)	Not enough to correct low iron
Magnesium	A small amount (around a tenth of the NRV or less)	You’d need food or a separate supplement
Calcium	Little to none	Doesn’t cover calcium at all

Why would a coeliac take a multivitamin at all?

Because coeliac disease can mess with absorption. The NHS page on complications of coeliac disease lists iron deficiency anaemia, vitamin B12 or folate deficiency anaemia and osteoporosis among them, especially before diagnosis or when gluten is still getting in. And the NHS vitamin D guidance says everyone in the UK should consider 10 mcg a day in autumn and winter anyway.

So a good multi makes sense as a backstop. But it’s a backstop, not a treatment. If you’re newly diagnosed, get your bloods checked first. Low iron, B12 or folate usually needs a proper dose from your GP, and a multivitamin won’t come close. I’ve covered the common gaps in more detail in coeliac disease and vitamin deficiency.

Is it OK if you’ve got IBS as well?

It was for me. I’ve got IBS alongside coeliac disease, and I had no bloating or upset while taking it. But IBS is personal, and what’s fine for my gut might not be fine for yours.

One thing worth knowing: Performance Lab describes the capsules as “prebiotic” because they’re made from pullulan (fermented tapioca). It’s a tiny amount and it didn’t bother me. If you’re in the middle of a low-FODMAP elimination, though, bring in one new thing at a time so you know what’s what, and run it past your dietitian.

Where does it fall short?

• Iron and calcium. These are the two that matter most for a lot of coeliacs, and this multi barely touches them. That may be deliberate in a men’s formula, but it’s worth knowing.
• Four capsules a day. Performance Lab says the extra cofactors need more capsule space. They’re small, but it’s still four more things to remember. Their page says you can take two to four.
• The price. It costs a lot more than a supermarket multivitamin. See below.
• Doubling up on vitamin D. If you already take a vitamin D supplement, add up the total before you take both. I’ve covered one in my Performance Lab D3+K2 review.

What should a coeliac look for in any multivitamin?

Whether you go for this one or something cheaper, these are the checks I’d make:

1. A clear gluten-free statement. In the UK, “gluten free” on a label means 20 parts per million or less (Coeliac UK explains the gluten-free labelling law). If a supplement doesn’t say it, don’t assume.
2. The full ingredients, not just the nutrients. Fillers, coatings and binders are where wheat starch or barley can sneak in. Read the “other ingredients” line.
3. What your bloods actually say. If you’re low in iron, B12, folate or vitamin D, you want a dose that fixes that, which usually means something from your GP rather than a multi.
4. Doubling up. Add together everything you take. Vitamin D is the easy one to overdo if you’re also taking a separate D supplement.
5. Whether you’ll actually take it. Four capsules a day suits some people and not others. The best multi is the one you don’t forget.

How much does it cost in the UK?

Around £33 to £44 for a month’s supply, checked September 2026. £44 is the one-off price. Subscribing or buying several boxes brings it down to about £33 a box, roughly £1.10 a day. There’s a 30-day money-back guarantee.

A basic supermarket multi costs far less. You’re paying for the formula, the clean label and the capsule.

Would I buy it with my own money today? Probably not, and that’s not a knock on the product or the brand. These days I see a functional medicine doctor who gives me bespoke advice on what to take, so a one-size-fits-all multi doesn’t really fit my routine any more. Not everyone can or wants to go down that route, though. If you just want one solid, gluten-free daily multi and the price works for you, this is a good one. Just get your bloods checked through your GP first, so you know what you’re actually covering.

How do you take it?

Performance Lab recommends two capsules in the morning and two in the afternoon, with or without food. If you take any regular medication, check with your GP or pharmacist before adding a supplement.

Who is it for, and who should skip it?

Worth a look if you’re a coeliac man who wants a clean, gluten-free, vegan daily multi with decent vitamin D and B vitamins, and the price doesn’t make you wince.

Skip it (or talk to your GP first) if you’ve been told you’re low in iron, calcium or B12, you’re on medication that interacts with supplements, or you’d rather spend less. A cheaper multi and a targeted supplement your GP recommends might do more for you.

Quick questions

Is there a women’s version?

Yes. NutriGenesis Multi for Women is a separate product with a different formula. Check its label rather than assuming it matches the men’s.

Can I take it with Performance Lab D3+K2?

Add up the vitamin D from both first. The multi alone gives 25 mcg, and the NHS’s safe upper limit for vitamin D is 100 mcg a day for adults. If you’re unsure, ask your GP or pharmacist.

Will it fix low iron or B12?

Unlikely. The iron dose is small, and a diagnosed deficiency usually needs a treatment dose your GP will set. Think of a multi as cover for small gaps, not a cure for big ones.

A multivitamin can’t make up for gluten still getting into your diet. Get the diet right first. Then something like this fills the smaller gaps.
